lCAR CONVEYER.

SPECIFICATION forming part of Letters Patent No. 721,336, dated February 24, 1903.

Application inea May s1, 1902.

To a/Z whom t may concern,.-

Bo it known that I, HARRY JOHN SMITH, a subject of the King of Great Britain, (but having declared my intention-of becoming a citizen of the United Statos,) residing at Philadelphia, inthe county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvemonts'in Car Conveyors, of which the following is a specification.

My invention relates toimprovements in conveyor-cars; and it consists of an electrically-operated car or trolleyfcar provided with a system of elevators for handling finely-divided coal or coke, commonly known as smalls, which accumulates in largo quantities about the doors of coking-ovons and which must be removedv from time to time, so that it will not choke the passage-way and interfere with the working 'of the ovens. In practice heretofore this waste product (small coke) has been removed by means of mulecarts, with the resulting evils that much time has been consumed in removal and much of the marketable product hasbeen crushed and rendered useless by the maneuvering of the carts and drivers in getting the waste material-or smalls away from the ovens.

In carrying out my invention the conveyorcars are caused to travel upon tracks mounted above the ovens, and the waste product be; low is reached by meansof extending conveyor mechanism which can be drawn upward or folded over the car when the same is loaded and ready to be removed to the dump-- ing-ground or incinorating-furnaces, where the waste product is disposed of.

My invention will be more fully understood by reference to the accompanying drawings, in whichp Figure 1 illustrates a vertical section of a coke-furnace with a conveyor-car constructed in accordance with? my invention arranged above the furnace-and having tho conveyors. extended to receive the waste product from below. Fig. 2 is a side elevation of the fur-, naces and car relatively in the same position as shown in Fig. 1.- Fig. 3 illustrates an onlarged front elevation of the gearing and connecting parts for operatingthe two'conveyers. Fig. 4 represents an enlarged front elevation of the parts shown in Fig. 3, and Fig. 5 illustrates an enlarged vertical sectionon the lino 5 5 of Fig. 4:.

Referring to the reference-letters of the srie No. 109,645. (No man.)

drawings, A A represent two of the series of coke-ovens, which are arranged in a double row in a long lino or battery and operated from opposite sides through doors A A'. Above the ovens is a railway B, upon which travels the car conveyor O forming the subject-matter of my invention. Along the sides of the ovens are arranged a series of supports B', to

which is attached a trolley-wire B2, which may be connected to a source of electrical energy to propel tho car and its operating parts through the medium of a trolley-wheel B3 and polo B4. On each of the sides of the car C is a supporting structure or framework D, rigidly united to the car and provided with bearings d and d', in which are supported shafts d2 and d3, supporting sprocket-wheels d4 and d5, which carry the endless conveyor mechanism D. Above the framework D is con- -structed a guideway E, formed of parallel members e and e', arranged in pairs somo distanco apart, so as to leave a space c2 to rev ceive the shaft f of a conveyor mechanism F.

The conveyor mechanism Fis supported in a channel-shaped frame F', one end of which is furnished with bearings f2 and with a hopper F?, into which the small coke is shoveled, so as to be picked up by the buckets flo of the conveyer mechanism. The opposite ond of frame `F is guided between the structural parts of ,the guideway E, and being journaled to the shaft fby bearings f3 is carried with the shaft as the conveyor mechanism is lifted. The shaftfis Vprovided with a gear-wheel f, which when the conveyor mechanism is in position shown in Fig. l of the drawings engages the tooth of a goar-wheolf12, which in turn engages the teeth of a gear-wheel f 13, mounted upon the shaft d3.- f

The power for driving the conveyor is obtained from an electric motor G, supported on the front platform of the car, on the shaft g of which isa sprocket-wheel g', which carries a sprocket-chain g2, passing around a -sprocket-wheel g5.

IOO

with au opening f 21, through which the buckets f discharge their contents into a hopper H, located so that the buckets of the conveyer D may readily gather up the material and carry it into the car C.

When the car (l has been loaded, the conveyer mechanisms F F on both sides of the car are drawn up over the conveyers D D by windlasses I I. As both are the same in character, a description of one will suice for.

both. The drum I is operated from the motor G by a sprocket-wheel t, a sprocket-chain 2l', and sprocket wheel i2, which latter is mounted upon the shaft I2. The drum I of the windlass is provided with a rope Z, which passes from the drum to a cross-rod Z in the hopper F2. When the conveyer mechanisms D and F are operating to load the car, the upper end of the rope Z is released from the drum I', so that the drum will revolve without effecting the lifting of the conveyer mechanism F; but when the rope Z is linked or otherwise fastened to the drum the conveyer mechanism will be lifted and at the same time disengaged from the mechanism by which it is caused to revolve.

A clutch mechanism may be arranged upon the shaft g of the motor, so that the winding mechanism may be thrown out of action when the conveyers are operating. When the car C has been illed and the conveyers F have been drawn up and folded over the car, the car is then moved over the railway B to the dumping-ground or to an incinerating-furnace, where the contents are discharged through one of the chutes C', leading from the bottom of the car and controlled by a suitable gate.

It will be understood that my invention is not limited to details of construction except where specifically pointed out in some of the claims. In others myinvention contemplates, broadly, the principle of a conveyer-car, as will be hereinafter fully defined.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-
